INSERTABLE JOINT.

Application filed January 25, 1923i. Serial No. 614,865.

To all whom t may concern:

Be it known thatl, JOHN J. MEYER, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the, county and State of New York, have invented a new and Improved lnsertable Joint, of which the following is a full, clear, and exactdescription.

This invention relates to an insertable joint for soil pipes and has for an object to provide an improved construction whereiny a joint may be readily made without disturbing the upper part of a pipe or the lower part. v

A further object of the invention is to provide an improved form of joint which is a division in part of my prior application, Serial No. 480,294.

A still further object is to provide a construction wherein one or more sleeves or nipples may be inserted laterally or transversely of the pipe.

An additional object is to provide an insertable joint for soil pipes wherein a specially constructed hub is provided which acts in the capacity of an ordinary hub and in addition as enclosing and retaining means for inserted portions of pipes andas a connecting member for connecting the inserted section with the superimposed section. f

In the accompanying drawing- Figure 1 isl a-.raginentary view of a soil pipe extending through two doors of a, building with certain :parts broken away illustrating an embodiment ofthe invention. Figure 2 is an enlarged fragmentary view of the upper part of the joint shown in Figure 1, the parts being in the position immediately after insertion.

Figure 3 is a view similar to Figure 2 but showing the parts in operative position and ready for receiving the packing.

Figure 4 is a view similar to Figure 8` but showing a modified construction of hub wherein one or more ring or sleeve sections may be used.

Referring to the accompanying drawing by numerals, 1 and 2 indicate the ioors of a building through which a soil pipe 3 eX- tends. The soil pipe may be of any desired height and connected in any desired manner .with the various fittings of the building. Under some circumstances, it may be desired to add a new section tothe soil pipe at some convenient point, kas for instance, section fl which is a branch section or pipe designed to present an auxiliary opening. y

`When it is desired to put in a new section similar to section fl, it will be necessary to remove one of the sections of the soil pipe and in such removal the particular section is broken or cut. After the desired section or sections have been removed, pipe et is inserted as shown in Figure 1 and then an inserted joint section provided which consists of a lower section 5 of the same diameter throughout and` adapted at its lower end to lit into the bell or hub 6 or' section 4f while at its upper end it is provided with threads 7 for receiving the internally threaded section 8 of the bell or hub 9. It will be noted that the upper end of the section 5 isl an appreciable distance below the lower end of the superimposed section 10,. To take care of this space and at the same time provide a proper support for the section 10 and other sections above the same, a nipple 11 and asleeve 12 are inserted and arranged as shown in Figures 1 to 3. It will be noted fromFigure 1, that after the parts have been arranged as shown in Figure 1, suitable packing 13 is provided in the hub 9. The nipple 11 is provided with a tubular section and an annular flange la at the upper end forming in connection with the shoulder 15 of hub 9 a false bottom for the hub. rlhe nipple 11 rests on the upper end of the sleeve 12 which sleeve in turn rests on the upper end of the section 5 and is held against lateral movement by an annular interiorilange 16 which properly centers the sleeve while thevllange 14 causes a proper centering of the nipple 11.v

lt will be noted that the hub or bell 9 is provided with an upper portion 17 which is in thegform of the usualbell, said upper portion merging into a thickened portion 18 which carries a shoulder 15, said thickened portion also merging into an intermediate section 19 and said intermediate section merging into a lower' section 20, which lower section carries the annular flange 16 and the threaded section 8. When the inserted joint is being placed in position, the nipplell is inserted into the hub 9. The hub 9 is then slipped over the lower end of the superimposed section l0, the section is then inserted until the parts assume the position shown in Figure 2. The sleeve 12 is then placed in position by a lateral transverse movement; This sleeve is made ofthe proper length or is cut od from a section of pipe so that it will be of the proper length to lill in the space between the section 5 and section 10 not occupied by the nipple 11. After the parts have been arranged as shown in Figure 2, the hub 9 is lowered and is screwed into position on the section 5V as shown in Figures 1 and 3. After the partsghave been thus assembled, the packing 13 is placed in position, which packing is oi' any usual or preferred kind.

Figure 4 discloses a modified construction wherein an internally and externally threaded ring 21 is screwed onto the threaded section 17 of pipe 5, said ring being also designed to accommodate the threaded section oi the hub 9. The ring 21 acts to form a flange or enlargement for the section 5 and readily supports one or more rings or sleeves 22 which are adapted to be placed in laterally before the hub 9 is lowered to the position shown in Figure 4. It will be noted that the rings or sleeves 22 have the same bore as section 5 but eX- tend outwardly into contact or almost contact with the hub 9 whereby ay false bottom is provided for the hub which is in align ment with the lower end of the superimposed section 10. Packing 13 may be arranged in this form of hub in the usual manner.

It is to be understood that a pipe having one or more branch openings or the usual strengthening bead at the end opposite the threaded end of pipe section 5, shall be considered uniform in diameter throughout as well as an ordinary straight pipe within the meaning of the speciiication and claims, as these features do no eilect the function of the threaded end and associated parts forming the joint.

1. An insertable joint for soil pipes and the like comprising a section of pipe of uniform diameter throughout having threads thereon adjacent the upper end, a hub for said section having at the lower end an internally threaded portion adapted to be screwed onto said section, and a plurality of tubular supporting members arranged in said hub and acting as spacing means for supporting the waste pipe above the hub, said tubular members resting on the pipe section.

2. An insertable joint for soil pipes and the like, comprising a pipe section having external threads adjacent one end thereof, a tubular ring divided intotwo parts, one part of said ring constituting one pipe end and the other part of said ring constituting a second pipe end co-acting with the first mentioned pipeend, anda hub removably regatas mounted on the externally threaded pipe end, said rings and pipe ends to be confined within said hub, a `filler joint around one of the pipe ends.

3. iin insertable joint comprising a pipe section threaded at its upper end, the said threaded portion to be of slightly less eX- terior diameter than said pipe section, a supporting. tubular sleeve resting on the end ot said pipe section, said sleeve to be of slightly less exterior diameter than said threaded portion or the pipe section, a hub adapted to be screwed onto the threaded end of the pipe section. a. nipple of like exterior diameter as the sleeve positioned inside of the hub, and intended to rest upon the sleeve, hub adapted to telescope over the sleeve and nipple to allow the sleeve to be inserted from a lateral position when the pipe section isl vertical, said hubhaving its bottom threaded interiorly to screw onto the threaded pipe section ait'ter the sleeve and nipple are in position, a superimposed pipe o'tl larger exterior diameter than the nipple or sleeve resting on top of the nipple and a liller joint between the hub and superimposed pipe end.

4. An insertable joint for soil pipes and the like, comprising a tubular supporting nipple in continuous tubular aligmnent between two pipe sections of a pipe line, said nipple being inserted from a direction opposite to that of the pipe sections after said pipe sections are in normal position, said nipple resting in position by gravity, a hub having two ends, one of its ends screwed onto one of the pipe sections and its other end adapted to contain a filler joint around the end of the second pipe section, said nipple being enclosed by said hub.

5. In combination with a soil pipe line, a tubular nipple placed in tubular alignment between two pipe sections of said line from a direction opposite to that of the pipe sections, a hub removably screwed onto one of said pipe sections and a filler joint in the hub around the end of the second pipe section, said nipple being contained within said hub, said nipple to rest by gravity on the pipe section independent of the hub, said nipple being of sufficient length to fill the gap between the said two pipe sections to support the weight of the superimposed pipe sections, said tubular nipple having a thickness of wall more or less than the abutting pipe sections.

6. An insertable pipe joint, comprising two pipe sections, a hub having an upper tubular bore, a central tubular bore, and a lower tubular bore, a tubular supporting nipple slidably positioned below the upper bore, the upper bore being adapted as the filler joint portion of said hub, said nipple and the shoulder in the bottom ott the upper bore forming the said filler joint bottom, a

tubular supporting sleeve resting by gravity on one of the said pipe sections, said sleeve being inserted between the said pipe sections, and the said nipple by ajnovement in opposite direction to that of the pipe sections, said hub being adapted to telescope over said sleeve and said nipple when assembling the sleeve and nipple to join the hub to the said two pipe sections.

7. An insertable joint, comprising a pipe section, said pipe section having an exteriorly threaded portion at one end, a hub adapted to be removably screwed onto said threaded end, a multiple of tubular space filling and supporting nipples resting by gravity on the end of said pipe section, said nipples being independent of the side walls of said hub, a superimposed pipe section having one end resting upon the uppermost nipple within the hub and a iller joint aro-und said end of the superimposed pipe, said nipples and removable hub adapted to allow said nipples to be inserted between the two pipe sections from a direction opposite to that of the pipe sections.

8. An insertable joint, comprising two pipe sections of like interior and exterior diameters, a tubular nipple of less exterior diameter than said two pipe sections positioned between the said two pipe sections, said nipple practically forming and constituting the end of the upper pipe section, a hub having unequal bores, said hub adapted toteleseope over said nipple to give clearance to the lower end of said nipple to allow a tubular sleeve of like exterior diameter as the nipple to be inserted in a transverse direction between the lower pipe section and the lower end of the said nipple, the lower end of said huh being threaded interiorly for engagement with the exteriorly threaded upper end of the lower pipe section, said hub being limited in its upward movement by reason of said upper pipe section having a greater exterior diameter than said threaded opening in the lower end of said hub, said lower bore of said hub being capable of telescoping over said nipple and sleeve but not large enough in diameter to telescope over the upper pipe section5 a iiller joint in the hub to enclose said upper pipe end, the end of the threaded pipe section, the said nipple and sleeve and the end of the upper pipe section to be contained within the said hub.
